Title:
  update manager -d crashes after the first step

Status in “update-manager” package in Ubuntu:
  Incomplete

Bug description:
  So, it's very simple, I'm using ubuntu 11.04 64bits and when I try to
  upgrade to 11.10 by typing sudo update-manager -d, it crashes after
  the first step(updating the sources or something)

  All I get is this:

  extracting 'oneiric.tar.gz'
  authenticate 'oneiric.tar.gz' against 'oneiric.tar.gz.gpg' 
  Traceback (most recent call last):
    File "/tmp/update-manager-xixRQF/oneiric", line 7, in <module>
      sys.exit(main())
    File "/tmp/update-manager-xixRQF/DistUpgradeMain.py", line 199, in main
      if app.run():
    File "/tmp/update-manager-xixRQF/DistUpgradeController.py", line 1662, in run
      return self.fullUpgrade()
    File "/tmp/update-manager-xixRQF/DistUpgradeController.py", line 1570, in fullUpgrade
      if not self.updateSourcesList():
    File "/tmp/update-manager-xixRQF/DistUpgradeController.py", line 670, in updateSourcesList
      if not self.rewriteSourcesList(mirror_check=True):
    File "/tmp/update-manager-xixRQF/DistUpgradeController.py", line 490, in rewriteSourcesList
      distro.enable_component("main")
    File "/tmp/update-manager-xixRQF/distro.py", line 298, in enable_component
      if c.name == comp and c.parent_component:
  AttributeError: 'Component' object has no attribute 'parent_component'

  
  Any suggestions? Whould you like to see my sources.list ?
